摘要
利用同步时钟授时实现异地相量同步测量,研制一种双CPU结构的高性能同步相量测量装置。介绍了基于双CPU结构的同步相量测量装置的软硬件设计方案。针对硬件设计,介绍了数据采集单元、同步时钟单元、高速通信网络单元的设计;针对软件设计,采用嵌入式实时操作系统uC/OSⅡ开发软件,重点阐述软件的移植和任务的划分,uC/OSⅡ的引入使同步相量测量装置的开发和维护变得简单。通过高速以太网实现异地SPMU的互联,构建全网动态稳定监视与控制系统。
The deviationism phasor is synchronized measured based on GPS synchronized clock. A double CPU method of high performance synchrophasor measurement unit is designed. The software and hardware design of synchrophasor measurement unit are introduced based on the double CPU structure. The data collected unit, synchronized clock unit and high speed communication network unit are represented at hardware design aspect. The software is developed based on embedded real-time system uC/OS II and software transplanted and task divided at software design aspect are stressed. The development and service is easy with uC/OS Ⅱ. The deviationism SPMU is connected by high speed ethernet communication. The wide-area dynamic stability monitoring and control system is constructed.
